Along with the increasing maturity of the solar power generation pavement technology, the solar power generation pavement technology gradually starts to be tested and applied in roads. The solar power generation assemblies with different structural design principles and forms are developed in China, America, the Netherlands, France and other countries, and test sections with different scales and load grades are paved. Particularly, the traffic operation of a solar power generation road surface test section paved on a Chinese expressway marks that the Chinese solar power generation road surface technology has great breakthrough in the aspects of bearing capacity, anti-skid performance, power generation efficiency and the like and reaches the world leading level. According to construction of a solar power generation road surface test section of a highway in China, the technical problems that an inverter, a combiner box, information acquisition equipment and a power cable are reasonably arranged outside a road surface range, effectively fixed and protected safely can be considered for the solar power generation road surface. The photovoltaic industry is currently typically designed to place power equipment such as inverters on the supports that support the photovoltaic modules, either on masonry structures built on site, or in nearby photovoltaic power plants to which the power cables are buried. However, since the photovoltaic modules of the solar power generation road surface are directly laid on the road, no support is available, and the photovoltaic modules are distributed along the road in a belt shape, in order to reduce the power transmission loss and the cost, all the power equipment such as inverters cannot be intensively arranged in the photovoltaic power station, and therefore the photovoltaic modules should be arranged nearby outside the road surface according to the confluence position of the matrix string of the photovoltaic modules laid on the road. However, the highway outside the highway surface range is the slope position outside the fence, because the highway in the plain area is usually filled with embankments, the slope has a larger slope, it is difficult to dig grooves on the highway for burying power cables and constructing masonry structures, and the additional pressure generated on the slope is easy to cause slope collapse and instability damage. In addition, the solar power generation road surface laid on the expressway is a test application of the fusion development of traffic engineering and electrical engineering, and although the energy supply of electric facilities along the expressway is solved, new technical requirements are provided for electric power supporting facilities for collecting, converting and transmitting the electric power of the solar power generation road surface along the expressway. Technical requirements of safety protection, collision prevention, rain prevention, sun shading, ventilation, convenience in maintenance and the like are also required to be considered when the inverter and the power cable are arranged on a high-speed slope. Therefore, based on the construction of the solar power generation road surface test section of the Chinese expressway, no special electric power supporting facility and construction for the solar power generation road surface exist in the market through research, and therefore, the design of the electric power supporting facility and construction for the solar power generation road surface is very necessary.
